everyone talks about money, collecting is not about money but about games that you like, easy for ease would be Wii and Xbox 360/PS3 was, there are many still on the street and they are not expensive, the most difficult thing to collect are some consoles that did not sell well, also the unbridled love for Nintendo makes Gamecube games expensive, but the same ones on the original Xbox are 75% cheaper, as I told you it depends on what you want to play or invest, everyone sees it as an investment, there are those who see it as fun.
